EARL H. MONAHAN, OF H YANNIS, NEBRASKA.-

VEHICIzE SPRING CONSTRUCTION.

Specification of Letters Patent.

Patented July 16, 1918.

Application filed January '3, 1917. Serial No. 140,407.

To all whom it may concern:

Be it known that I, EARL H. MONAHAN, a citizen of the United States, andresident of Hyannis, in the county of Grant and State of Nebraska, whosepost-office address is Hyannis, Nebraska, have invented certain new anduseful Improvements in Vehicle Spring Construction, of which thefollowing is a specification. I

My invention relates to a spring construction and more particularly to avehicle spring construction.

The primary object of the presentinvention is to provide means which isarranged on the conventional type of elliptical springs now in use andwhich will render the springs stronger and will increase the life of thesame.

A second object of the invention is to provide n attachment forelliptical springs that will greatly increase the resilient quali .tiesof the springs.

Another important object of the invention is to provide an attachment ofthe above mentioned character which may be used in conjunction with anytype of elliptical spring now on the. market and which may be quicklyand easily applied to the.

same.

Still another object of the present invention is to provide anattachment of the above mentioned character which consists of few parts,is inexpensive to manufacture and which may be placed on the market at acomparatively low cost.

This invention consists of the constructions, combinations andarrangement of parts that will be hereinafter set forth in the followingspecification and illustrated in the accompanying drawings, in whichFigure 1 is a side view of a conventional elliptical spring having myinvention applied thereto.

Fig. 2 is a sectional view on the line 22 of Fig. 1 and showing myinvention in elevation.

On the drawings like characters of reference indicate like parts in allthe views.

Referring more particularly to the drawings, the numeral 5 designates aside bar of an automobile chassis and the numerals 6 and 7 designate thesections ofan elliptical spring. While I have shown one form ofelliptical spring, it is to be understood that any form of spring may beused in conjunction with my invention.

Mounted on the spring section 6 is a rectangular loop or sleeve 8 whichcarries a set screw 9 that is threaded into engagement with the sectionti to retain the sleeve or loop in position. Extending from oppositesides of the sleeve or loop 8 are laterally extending perforated cars10.

Arranged on the spring section 7 is a second sleeve or loop 11 which isretained in position by a set screw 12 and also has extending fromopposite sides thereof perforated cars 13. Both of these members 8 and11 are identical in construction. Extending through the perforated ears10 of the sleeve 8 and through the perforated ears 13 of the sleeve 11are relatively long rods 14 which are provided upon their upper-endswith heads 15 that rest upon the cars 10. These rods extend verticallyand upon opposite sides of the sections 6 and 7. Jam nuts 16 arethreaded upon the upper ends of the rods 14 and bear against the underface of the cars 10.

Disposed on the rods 14 are expansible springs 16 and 17; The lower endsof the springs 16 bear against the upper face of the ears 13 while theupper ends of the springs 17 bear against the under face of these ears.Nuts 18 are disposed upon the lower ends of the rods 14 and bear againstthe springs 18. It will be seen that the tension of these springs 17 maybe varied by the adjustment of these nuts. Also threaded upon the rods14 are nuts 19 which bear against the upper ends of the springs 16 bymeans of which a the tension of the springs may, be varied. It will beseen that the movement of the section 7 is between the rods 14 and thatthese rods will prevent this section from moving laterally.

Having described the preferred embodiment of my invention, I desire itunderstood that the same is susceptible to various alterations andmodifications that may fall within the scope of the appended claim.

What is claimed is:

The combination with upper and lower elliptical springs havingcorresponding ends suitably connected; of a sleeve receivin a portion ofthe upper elliptical spring an clamped thereto, said sleeve beingprovided upon its opposite ends with horizontal ears which are rigidlysecured thereto and provided with vertical apertures; a secon sleevereceiving a portion of the lower elliptical spring and clamped th'ereto,said second sleeve being provided upon its opporods being arranged toreciprocate within site ends with horizontal ears'which are. mg thevertical apertures in the ears of the secidly secured to the sleeve andhave vertical ond named sleeve, compressible coil springs apertures;rigid rods vertically disposed surrounding the rods above and below the5 upon opposite sides of the elliptical springs last named ears tocontact therewith; and and having their upper ends clamped withinadjustable elements carried by the rods to the vertical apertures in theears of the first engage the ends of said coil springs. named sleeve,the lower portions of these EARL Ha MONAHAN.
